JOSEPH WALTER RABBIT, OF AROMA, INDIANA.

PORTABLE FURNACE.

SPECIFICATION forming part of Letters Patent No. 321,332, dated June 30,1885.

Application filed April 9, i885. (No model.)

T0 @ZZ whom, it may concern:

Be it known that I, JosErH NV. BABBIT, a citizen of the United States,and a resident of Aroma, in the county of Hamilton and State of Indiana,have invented certain new and useful Improvements in Portable Furnaces;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which forma part of this specification,and in which- Figurel is a side view of my improved portable furnace,showing the same to be constructed of two cylinders or compartments.Fig. 2 is a top or plan view ofthe same. Fig. 3 is a perspective viewshowing the manner of constructing the connecting-flue. Fig. 4 is ahorizontal sectional view ofthe furnace, looking downwardlyintothe same.Fig. 5 is a detail view of one of the plates forming the tops of theconnecting-flues,and Fig. Gis a top view showing my improvement appliedto a furnace having` three cylinders or compartments.

The same letters refer to the same parts in all the figures.

This invention relates to portable furnaces for agricultural anddomestic purposes 3 and it consists in the improved construction of a furnace of this class having two or more cylindrical drums orcompartments, as will be hereinafter more fully described, andparticularly pointed out in the claims.

In the drawings hereto annexed, A and A denote two sheet-metalcylinders, open at the top and bottom,and provided near their upper endswith metallic bands or hoops B, serving to brace and stifen thecylinders, and provided with downwardly-extending legs C C, upon whichthey are supported. The legs are sec cured, near their lower ends, tothe sides of the cylinders by means of bails D, thereby increasing therigidity of the said legs and strengthening the device generally.

One of the cylinders,A, is provided with a door, E, through which fuelmay be fed into the furnace; and the other cylinder is provided with athimble or collar, F, surrounding an opening, G, and to which apipe orsmokestack may be attached. The cylinders A and by a plate, K, cut of'ashape to iit the flue.

In this manner the two cylinders or drums are connected rigidly, theconnecting-flue H being constructed with double sides formed by theoverlapping wings or flaps J, as will be seen more clearly by referenceto Fig. L1.

It will be noticed that this way of forming the flue H makes it three-sided,or, rather, with` out a bottom. This permits the re to beplaced underneath both or all of the kettles being heated, and itwillalso permit of the use of long sticks of wood that will reach throughboth parts of the furnace.

My improved furnace may, when desired,be constructed of more than twodrums or cylinders, as will be seen in Fig. 5 ofthe drawings, wherethree such drums or cylinders have been shown. In such case the severalcylinders are connected by dues H, of the construction alreadydescribed, and the two end cylinders are provided, respectively, with adoor, and with a thimble for the attachment of a smokestack.

The operation and advantages of this invention will be readilyunderstood from the foregoing description, taken in connection with thedrawings hereto annexed. Kettles or caldrons may be readily fitted tothe upper ends of the cylinders. Vood, coal, or other fuel may be used,and grates may be provided for the lower ends of the drums orcylinders,when desired.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. A portable furnace consisting ofa series of two or more drums or cylinders open at their upper and lowerends, and connected by bottomless flues or passages constructed of wingsor iiaps cut from the bodies of the said ICO cylinders, placed togetheroverlapping each legs, and a door and a pipe collar orthimble other,connected by riveting, and provided attached, respectively, to the frontand the with top covering-plates,substantially as hererear end cylinder,substantially as herein dein described, for the purpose set forth.scribed, for the purpose set forth. 15

In a portable furnace, the combination of In testimony that I claimthe foregoing as my a series of drums or cylinders, bottolnless fluesown I have hereunto afxedmy signature in or passages connecting thesame,and constructpresence of two Witnesses. ed of overlapping Wings orflaps cut from the JOSEPH WALTER BABBIT. sides of said cylinders,andsuitable top plates, Witnesses:
